the node value or null.
Standards information
- Document Object Model (DOM) Level 1 Specification, Section 1.2
Remarks
If the object is a TextNode object, the nodeValue property returns a string that represents the text that the node contains.
You cannot use expressions to change the nodeValue of a TextNode object.
If the object is an attribute object retrieved from the attributes collection, the nodeValue property returns the value of the attribute if it has been specified, or null otherwise.
If the object is an element, the nodeValue returns null. Use the nodeName property to determine the element name.
Examples
The following code example alters the text of the specified list item by setting the nodeValue property of the text node that is contained by that list item.
<!DOCTYPE html>
<html>
<head>
<title>nodeValue</title>
</head>
<body>
<p>Click the bulleted list:</p>
<ul>
<li>Old Node Value</li>
</ul>
<script>
document.getElementsByTagName('li')[0].addEventListener('click', fnChangeValue, false);
function fnChangeValue(evt) {
var li = evt.target;
var textNode = li.childNodes[0];
textNode.nodeValue = "New Node value";
}
</script>
</body>
</html>
